if you want to pass in parameters into a Silverlight application from your calling web page you have to specify and assign the parameters inside the <object ... /> tag that you're using to embed the Silverlight app.
An example for such a parameter could be:

<object data="..." type="...">
  <param name="Parameter1" value="Value1" />
</object>

Inside the Application_Startup method (App.xaml.cs) you can query these parameters from the StartupEventArgs' InitParams collection.

If you just want to the get the hosting URL you can use this property from everywhere inside your Silverlight application:

System.Windows.Browser.HtmlPage.Document.DocumentUri
